This mystery becomes their “current” case to solve: The Case of the Electrical Mystery.The tree house detectives are... Topics: NASA, electricity
In Patterns, Functions and Algebra: Wired for Space, students will learn how patterns, functions and algebra can help NASA engineers design new ways of propelling spacecraft and how electricity and magnetism are being used to replace the fuel-consuming rocket propulsion commonly used to deliver a push to spacecraft. Students will discover three projects that use electromagnetism in a dynamic way: the Magnetic Levitation Launch System (MagLev), the Propulsive Small Expendable Deployer System...

Produced by Westinghouse during WWII, this film explains how electronic vacuum tubes work from the simple diode (single pole switch) to the complex Cathode Ray tube. As the film shows, tubes with grids can be used as electronic amplifiers, rectifiers, electronically controlled switches, oscillators, and for other purposes. Some of the innovations shown in the film include tubes used as rectifiers (for AC/DC conversion and production of metal such as aluminum), an early kind of tube based... favoritefavoritefavoritefavorite ( 1 reviews ) Topics: Vacuum tube, Air purifier, Westinghouse, Power rectifier, Amplification, Steampunk, Electronics,...

RURAL ELECTRIFICATION IN OHIO features three films commissioned by Rural Electrification Administration for the U.S. Department of Agriculture, and created by legendary filmmakers Pare Lorentz and Joris Ivens. The landmark 1940 documentary Power and the Land tells the story of the Parkinson family, farmers in rural Ohio who electrified their farm with the help of a REA loan. Before electrification, work was done in old-fashioned, manual-labor intensive ways—water was carried by hand from the...
